Vertical probes collect data in the A and B axes. They are the most commonly used probes.
Readings taken from an inclinometer probe are actually deviations from the vertical over the
distance between the upper and lower wheels. When the probe is passed through the
inclinometer casing, a reading is taken every 0.5m (or 2ft.). When the probe is at rest, the
MEMS accelerometers sense the inclination of the access tube in two planes. This
inclination is displayed in terms of
angular deviation
, which is recorded at that particular
depth.

The function of the MEMS Horizontal Inclinometer Probe is very similar to the standard
biaxial (vertical) probe. Each individual survey requires the probe to be drawn or pulled
through the casing, then reversed and passed through the casing again (probe is reversed
end for end
– not rotated axially 180° as in a vertical inclinometer survey). Measurements
are collected at 0.5m intervals with the metric probe or 2 ft intervals with the imperial probe.
